I bought an external Lacie DVD burner (firewire). No matter what I do it won't mount on my desktop. I tried other devices (Lacie firewire ext. HD) but I had the same problem. It seems my firewire ports had a problem. I then bought a firewire card and installed it in slot 5. It showed up in my system profiler (slot 5). But still after trying and trying I can't get the DVD drive to show up on my desktop. I downloaded and ran all the Lacie software updates, etc.

The reason I bought the drive in the first place was to install Tiger 10.4.6 (DVD). My system is now at OSX 10.3.9. My G4 is a Quicksilver 733Mhz
